A reasonable neighbor (even a kid) does not kick-in another persons door late at night.
A reasonable home owner does not assume that a deaf mute may be trying to gain entry (this sounds like some plot from Murder She Wrote).
A reasonable person would rightly assume that harm is intended by the door crasher.
Reasonable does not mean a home owner has to be telepathic or hear like a dog.
Also, if you do smoke the door crasher and it turns out it was a crinminal assualt, is it really so wrong to testify that the assailant made harsh verbal threats and that you thought you heard the voices of accomplices?
Didn't the guy who shot the Japanese tourist kid (who did not understand the word "Freeze") get off?
